Does Purview DLP Cover Computer-Using AI Agents?
Assess Purview DLP coverage for AI agent sessions handling PII and payments, including screenshot inputs, file uploads and endpoint controls.
Research topic
data exfiltration
Research on data exfiltration for AI agent workflows, with tokenization, access controls and evidence for teams handling sensitive business data.
Can an AI Agent Exfiltrate Data Through a Markdown Image or URL?
Yes. If the client fetches images or links in the agent's output on its own, data in the URL leaves the session. Check how output is rendered.
Does Blocking Untrusted Websites Protect AI Agents?
Partly. URL filtering removes hostile sites, but trusted domains host injected instructions and exfiltration endpoints. Check what the agent holds.
Does Prompt Injection Expose Customer Records?
Yes, when the injected agent sees real customer data and can send outward; attacks leaked data at 20 to 70 percent. Check what the model holds.
How Do AI Agents Bypass Company Data Protection Rules?
Not by breaking rules but by passing beneath them: DLP watches files and uploads while an agent reads the screen. Check what sees what the model received.
What Is the Lethal Trifecta for AI Agents?
Three capabilities in one agent: private data, untrusted content and external communication, which turn a planted instruction into theft. Remove one.
Can a Browser Agent Be Tricked Into Pasting Sensitive Data Into a Chat?
Yes: an injected instruction to paste what the agent just read is the simplest exfiltration. Vendor controls govern typing, not what the model was shown.
How Do Attackers Steal Credentials Through Prompt Injection?
They plant instructions in content an agent reads that tell it to collect a credential it can reach and send it out. Check the lethal trifecta and remove .
How Do I Control Where a Browser Agent Can Submit Data?
With two settings: a domain allowlist that bounds navigation and a destination policy that bounds where a real value is released.
How Do I Limit Where a Hijacked Agent Can Send Data?
A hijacked agent can only send to places it can reach, so bound the network first, bound where real values resolve second.
How Do I Limit Where an AI Agent Can Send Data?
With three fields in the grant: which hosts the run may reach, which destination may receive a real value, and what the model reads on the page.
What Can a Hijacked Agent Leak If It Only Has Placeholders?
Tokens, page text the policy left in the clear, and the fact of the action, but not the values behind them. Check which fields are tokenized.
RedactSure vs Mimecast Incydr: 2026 Comparison & Alternative
Mimecast Incydr scores and blocks data movement by people and agents, while RedactSure, a Mimecast Incydr alternative built for AI agents, replaces identifiers with tokens before any model reads the screen. RedactSure is an alternative way to think about agent browsing security, because it protects sensitive data as it is rendered on a screen, before an agent uses it.
Can AI Coding Agents Read Your API Keys?
In all 6 leading AI coding agents reviewed, the secrets a team gives the agent are placed in environment variables the agent can read, by the vendor's own documentation. Only 2 of the 6 ask a person by default before the agent reaches the network. The safest sandboxes give the agent a placeholder instead.
How Many Security Flaws in AI Agents Were Published in the Last Year?
616 security flaws in AI agents, MCP servers and agent platforms were published from October 27, 2025 to October 26, 2026, up from 92 in the year before. 207 of them let an attacker get data the agent, its tools or its server could reach. These are published records, so the count also reflects a fast-growing category.
